Zhu Ling (Polypori Sclerotium, 18 zhu, peeled) Ze Xie (Alismatis Rhizoma, 1 liang 6 zhu) Bai Zhu (Atractylodis Macrocephalae Rhizoma, 18 zhu) Fu Ling (Poria, 18 zhu) Gui Zhi (Cinnamomi Ramulus, half liang, peeled). The above five herbs are
pounded into a powder. Mix with rice water and take orally. One fangcun bi (a measure of volume) per dose, three times daily. Drink plenty of warm water after administration; recovery occurs when sweat appears. Adjust care according to these instructions. Taking the powder aims to keep the medicinal effect lingering in the chest; drinking warm water helps disperse Ying and Wei (Nutritive and Defensive Qi) through the qi of water.
Taiyang disease (disease pattern caused by pathogenic invasion of the Taiyang channel), after inducing sweating, if profuse sweating occurs, leading to dryness in the Stomach, restlessness, inability to sleep, and desire for water, give small amounts of water frequently. When Stomach Qi harmonizes, the patient recovers. If the pulse is floating,
urination is difficult, accompanied by slight fever and excessive thirst, Wu Ling San (Five-Ingredient Powder with Poria) is indicated. Dryness in the Stomach with desire to drink indicates a lack of fluids; providing water leads to recovery. Difficulty in urination with desire to drink indicates retained water; promoting diuresis leads to recovery. Although both present with thirst, the treatment methods differ because the manifestations of thirst and accompanying symptoms vary.
After inducing sweating, if the pulse is floating and rapid, accompanied by irritability and severe thirst, Wu Ling San (Five-Ingredient Powder with Poria) is indicated. Incomplete resolution of sweating implies retained fluid retention.
Wind-stroke with fever, unresolved after six or seven days, accompanied by irritability, presenting both exterior and interior signs, with thirst and vomiting immediately after drinking water, is named Shui Ni (Water Reversal). Water accumulation in the chest prevents it from accommodating new water. Wu Ling San (Five-Ingredient Powder with Poria) is indicated. Gui Zhi (Cinnamon Twig) treats the exterior, while the other four herbs treat the interior. Drinking warm water to induce sweat resolves both exterior and interior conditions simultaneously.
Originally due to erroneous purgation, epigastric fullness and stuffiness occurred. Given Xie Xin Tang (Drain the Epigastrium Decoction), but the fullness did not resolve. If the patient experiences thirst, dry mouth, irritability, and difficulty in urination, Wu Ling San (Five-Ingredient Powder with Poria) is indicated. If treating fullness fails to resolve it, and thirst ensues, it is due to water retention in the epigastrium, not mere fullness.
In Taiyang disease, a slow pulse at the Cun position, floating at the Guan position, and weak at the Chi position all indicate deficiency patterns. If the patient has fever, sweating, aversion to cold, no vomiting, but only epigastric fullness, this results from the physician's erroneous purgation, constituting mismanagement. If no purgation was performed, and the patient is not averse to cold but is thirsty, the condition has transferred to Yangming disease (disease pattern involving the Yangming channels and organs). This represents excess pathogenic factors. Frequent urination leads to hard stools; even without defecation for ten days, there is no distress. For those desiring water, provide small amounts frequently. Rescue according to principles, treating based on specific symptoms without rigid adherence to a single method. For thirst, administer Wu Ling San (Five-Ingredient Powder with Poria). If thirst persists, Wu Ling San (Five-Ingredient Powder with Poria) remains one therapeutic option.
Huo Luan (acute vomiting and diarrhea syndrome) with headache, fever, body pain, predominant heat sensation, and desire for water is treated with Wu Ling San (Five-Ingredient Powder with Poria). This also employs a method of simultaneous treatment of exterior and interior conditions.
